This patch contains the common code, which is used by all HID sensors.
There are some common set of attributes, which every hid sensor
needs it. This patch contains all such attributes processing.
Also the trigger interface is common among all HID sensors. This
patch contains common trigger functions utilized by all HID sensors.

Adding processing for HID Sensor usage table as defined by
HID 1.12, Request #: HUTRR39, dated 05 May, 2011.
This driver uses HID driver framework to register, send and
receive events.
This uses MFD framework, so that actual processing for a
specific usage id can be done in a different driver. For
example an accelerometer driver can be a separate driver and
use the interface provided by this driver to register for
events.

USB autosuspend suspends vhci_hcd. In this process hcd_bus_suspend gets
executed which puts vhci_hcd in suspend state and calls vhci_hub_status.
vhci_hub_status function checks hub state and if it is in suspend state,
usb_hcd_resume_root_hub gets executed which resumes hub and if hub is
idle, again autosuspend puts it in suspend state and this goes on.

vhci_hub_status should resume hub only when hub port is in suspend state
and hub port status has changed.

Almost all of usbip assumes that the_controller->lock is acquired
before vdev->priv_lock. The exception is in
vhci_device_unlink_cleanup(), where locks are acquired in the
reverse order. This leads to occasional deadlocks.

Fixing this is a bit fiddly, as the_controller->lock can't be held
when calling usb_hcd_unlink_urb_from_ep() in the middle of the list
traversal. As I can't rule out concurrent callers to this function
(perhaps it is safe?), the code here becomes slightly uglier - when
locks are dropped in the middle so the list may have emptied itself
(not even list_for_each_entry_safe is safe here).

If "pool_id" is negative then it leads to a read before the start of the
array.  If "cli_id" is out of bounds then it leads to a NULL dereference
of "cli".  GCC would have warned about that bug except that we
initialized the warning message away.

Also it's better to put the parameter names into the function
declaration in the .h file.  It serves as a kind of documentation.
